My first successful brisket!!

First one was small in weight but I made the mistake of applying same time 😟: next one was 10.33 lbs and was very good!! Smoked at 225degrees from 7:45am till 8:20pm turned off model 1400and it stayed in smoker about 40 min. It was very good, juicy, good bark and flavor was excellent( used salt pepper and paprika). I tried to go by temp but my probe wasn't cooperating.
